Abnormal Ekg Readings. The qt interval black double headed arrow is prolonged to 680 msec normal 300 440 msec with a qtc also of 680 msec normal 460 msec the t wave heights alternate blue arrows and such alternation is often a precursor to the more severe rhythm of torsades de pointes. The ecg readings can be interpreted in three ways. The table below lists many types of abnormal ekg which are described in this guide. Abnormal heart shape or size.
Abnormal ecg results are associated with conditions such as heart failure atrial fibrillation sick sinus syndrome and multifocal atrial tachycardia. Long qt interval and t wave alternans. This noninvasive test can measure many aspects from how fast the heart beats to how well its chambers conduct electrical. An abnormal ekg means that there is something unexpected in the ekg reading. The information is collected by placing electrodes at different points in the body like the arms and legs. The tracing shows a sinus rhythm at 60 beats min.
In this instance it can be an indication that the heart is working harder than usual to pump blood around the body.
When evaluating lethal rhythms on a 12 lead ekg it is important to remember the rhythm alone can be lethal as well as what the ekg is showing you in terms of heart function. The results can be an indication of several health issues such as. Long qt interval and t wave alternans. The qt interval black double headed arrow is prolonged to 680 msec normal 300 440 msec with a qtc also of 680 msec normal 460 msec the t wave heights alternate blue arrows and such alternation is often a precursor to the more severe rhythm of torsades de pointes. For example if there are 7 r waves in a 6 second strip the heart rate is 70 7x10 70. What an abnormal ekg means.
